The rated short-time withstand current (Icw) of 25 kA for 0.5 s tells you this disconnector coordinates with downstream protective devices that clear fast faults within that window, and the 52 kA making capacity (Icm) at 690 V means it can close onto a bolted fault without welding contacts. Isolation suitability per IEC 60947-3 is confirmed, with an 8 kV impulse withstand voltage (Uimp) and pollution degree 3 — so it's certified for safe visible isolation of a circuit, not just load breaking.
Fixed-mount, front connection both sides, 70 mm pole pitch — that's the standard ComPacT NS footprint, so it drops into an existing cutout or busbar system without re-drilling. The IP40 enclosure keeps dust and stray tools out of the switching chamber; IK07 means it survives a 2 J impact during installation. Ambient range of -25 to 70 °C operating and -50 to 85 °C storage covers unheated warehouses and outdoor cabinets in most climates.
